Detecting Apparatus

Abstract

A detecting apparatus includes a storage chamber containing a treating fluid. The detecting apparatus is internally provided with a sharp-pointed portion. The storage chamber makes a movement relative to the sharp-pointed portion and will be pierced by the sharp-pointed portion during the moving process. The detecting apparatus further includes a collecting chamber. The released treating fluid may flow into the collecting chamber which is disposed inside a first shell and used to contain a sample. An opening is disposed at an upper position of the first shell. The collecting chamber is internally provided with a testing element for detecting an analyte. The testing element is disposed on a carrier which has a specific matching form with the collecting chamber. A buffer solution is disposed in an independent chamber of the detecting apparatus. The carrier has a specific matching form with the collecting chamber in the first shell.
